Stereo Camera Rig in Parallel Evaluation

[icapathos]

I found an issue with Stereo Camera Rig in Parallel Evaluation.

I create a stereo camera rig and set keyframes in translate.

At the moment, Evaluation Mode is set to "Parallel".

Then, turn on "Safe Viewing Volume" and go forward and backward within time slider.

In the condition, Safe Viewing Volume is not following the camera.

I set to Evaluation Mode to "DG" and then Safe Viewing Volume is following the camera rig.

So, I suspect that Parallel Evaluation Mode is not working with Stereo Camera Rig.

Anyone knows about that or has solution?

Hi,

The issue is with Cached Playback, not parallel evaluation.

More specicially the stereoRigFrustum node used to draw the safe volume is not marked as a caching point by default.

To fix this you can either:
1) disable cached playback or

2) run the following Python command to mark the stereoRigFrustum node as a caching point.
Note: you would have to do this every time you start Maya

import maya.cmds as cmds
cmds.cacheEvaluator(newFilter='nodeTypes', newFilterParam='types=+stereoRigFrustum', newAction='enableEvaluationCache')
